Yes, this would be amazing!!!

It is currently so hard to visually skim boards for the right one, because they all get different generic icons, and while you can select your own icon they are all pretty meaningless and visually indistinguishable from each other.

The other alternative is to have to actually create/download an image then upload it as thumbnail.

But often the board will have something very recognisable/distinctive in it, so it would be amazing just to drag a square around a part of the board, or a frame and set it to the thumbnail!
